Ashton Kutcher Fires Back After Charlie Sheen Threat

“Two and a Half Men” star Ashton Kutcher has fired back at his predecessor Charlie Sheen, after Sheen threatened to put Kutcher on “a hospital food diet for a year.”

Kutcher offered a semi-veiled response on his Twitter account on Thursday, posting a picture of himself next to a sign bearing the “Two and a Half Men” logo with the message, “See you all tonight CBS.”

The hashtag for the message? “#stfu.” Which, for the acronym-impaired, stands for “Shut the f— up.”

For those who haven’t been following the back-and-forth that’s been unfolding between Kutcher and Sheen this week, Kutcher’s tweet might not seem to hold much meaning. But looking back on the growing acrimony between the two actors, the message appears to be a pointed missive reminding Sheen that Kutcher is the star of “Two and a Half Men” now, not Sheen.

The latest puddle of bad blood began to trickle when Kutcher appeared on “Jimmy Kimmel Live” this week and said that he wished Sheen — who was ousted from the show in 2011 — would “shut the f– up” already.
